Hi,

When I click rows on Grid1 I display results in Grid2, but when I uncheck the rows in Grid1, how do I clear the rows in Grid2?

Thanks,

Victor

Hi Victor;

Is this a web form a Windows form a WPF application?
Is this a master detail data grid view?
It would help to see the code.

You no need to clear rows of Grid2, if you don't want to show Grid2, You can just hide/show Grid2 on click of checkbox of Grid1.

Or here you can use Expand/collapse functionality;

Hi,

It is a windows application inn VS 2010, using the DataGridView. I would prefer to clear the rows than hide the Grid if possible.

Hi,

Below is the code I'm using in c1valuechange event of C1Screen2 to load C1Screen3.

 Dim FilteredDTA As DataTable
        Dim DVA As New DataView(dtsetLinkAOP5.Tables(0), SearchCriteria, Nothing, DataViewRowState.CurrentRows)
        FilteredDTA = DVA.ToTable
        If FilteredDTA.Rows.Count > 0 Then
        Me.C1Screen3.DataSource = FilteredDTA.DefaultView.ToTable(True, New String() {"COUNTRY", "FIF", "NAS", "QUANTITY", "PC"})
End If

To your question, "When I click rows on Grid1 I display results in Grid2, but when I uncheck the rows in Grid1, how do I clear the rows in Grid2?", try the following :

Grid2.DataSource = Nothing
